摘要：

An integral transform technique, the Pade-Laplace method, was adopted to calculate the number of discrete exponential components and the corresponding parameters from NMR spin relaxation decay curves. The results thus obtained can be improved by injection into an iterative program. This 'Pade-Laplace plus iterative' method was tested on simulated data of up to five relaxation times and then on experimental data obtained with a tube containing four manganese chloride-doped water samples. The results extracted from the low-resolution, low-field NMR signals of complex chemical and biological products are discussed.
